The terrifying mechanism explains how you might be deaf just because of listening to music on the road

Simply because. But how is the mechanism of this process?

It's not uncommon for a headphone to listen to music on the road. However, according to a recent audiologist, it seems that we - especially young people - still have not anticipated the harmful effects of this action.

Hearing sounds too loud will be annoying.

Specifically, William Shapiro, an audiologist from New York University Langone, said 1: 5 is the proportion of young people suffering from symptoms of hearing loss due to excessive exposure to noise . And the mechanism of this is related to hair cells.

In each ear, we have the inner structure called, with 15,000 hair cells . They have a sensory role, helping us to locate sound waves, but are extremely fragile and fragile. So, any damage to hair cells, our ability to sense hearing will be affected.

More importantly, hair cells do not recover on their own, so the damage is permanent. We will hear more difficult, wrong hearing, or even deafness if the eardrum is punctured.

But in fact, very rarely do we encounter noise outside the environment enough to cause damage to our hearing. The thing that can do that is just a headset - when a lot of people turn on the music, it's too big for the need.

"The earpiece is of course close to the ear, and the closer it is, the greater the sound pressure is created," Shapiro said.

"In essence, you are making the hair cells in the cochlea suffer pressure, which is gradually damaged over time. A volume increase of about 3 - 6 decibels is enough to double the pressure caused."

In fact, hearing the sound too loud will be annoying. However, many young people use headphones when walking on the road, where there are too many sounds that interfere. They immediately increase the volume, and the long-term effect is hearing loss.

How to ensure the safety of our ears?

According to Professor Shapiro: "If using headphones, the most standard rule is to hear the volume at 60%, and not hear more than 60 minutes / day."

For those who want to eliminate unpleasant sounds from the outside environment, noise-canceling headphones can be used.

"These are headphones that help reduce noise from the external environment, so you don't have to increase the volume from the headset."

Always keep the sound low, listen - that's the most important thing.
